Insulation fault locator, RR 5887
Type:
Monitoring Hardware
Description:
The locating current injector RR 5886 in connection with the insulation
fault locator RR 5887 monitors and localises insulation faults in complex
AC/DC networks (IT systems). The external current transformers work
independently of each other. They are simply connected to the measuring
channels of the insulation fault locator RR 5887 and are calibrated by it.
The number of measuring channels is increased by combining several
insulation fault locators via a RS-485 bus connection. The search for
insulation faults in extensive networks can be refined in this manner.
Two different alarm levels facilitate the timely detection of a dangerous
insulation state. The devices are operated easily and intuitively thanks to
automatic balancing and a clear layout of the setting elements. The early
detection and localisation of insulations faults permits their quick and
targeted correction. As user you will benefit from the operating reliability
and high availability of your system.
